Abstract

987,148. Valves. REDMAN TOOLS Ltd. Nov. 22, 1963 [Nov. 22, 1962], No. 44292/62. Heading F2V. [Also in Division B3] A valve assembly for controlling the discharge of fluid from a jack in a bending machine comprises a main valve 38 controlled by fluid pressure, supplied through pipes 75, 76 connected to each side of a control valve 52, and by a spring 45 compressed by an adjustable abutment 65. The pressure-drop across the valve 52 is effective to adjust valve 38. The setting of the control valve 52 is also adjustable, by a rod 77 operated by an eccentric 31, which may be locked externally of the valve casing.
